Abstract

Fluorocarbon coatings were developed with respectively 10%, 20% and 30% PTFE powder to prevent marine biofouling. Influence of content of PTFE on microstructures and roughness of coatings was investigated using SEM and roughometer. It was studied that the effects of coating roughness on settlement of benthic diatom and Ectocarpus by using biological microscope, stereo microscope, image processing and spectrophotometer. Results indicated that the surface roughness of coatings decreases and the quantity of benthic diatom and Ectocarpus reduces attaching onto the coating with the increase of content of PTFE in paint studied. Benthic diatoms attached much more on horizontal specimen than on vertical one; they prefer to settle onto the coatings that there are lots of micro-cracks in it. These results are helpful for developing new non-toxic antifouling paints.
